I run 14.4 in the stutterbox load areas.

To avoid knock during the launch limiter you have to ease into the throttle instead of mashing the pedal down. If I mash the pedal I see knock. If I gradually sink it to the floor there is zero knock.

 

I have noticed the same thing. I used to get knock around 10 counts, now I get none or 1-2 at most.

 

yeah i learned the hard way I saw 20+ counts one day @ the track , then it hit "ease my way there"

 

TouringBubble - I followed your guide on setting up the stationary rev limiter http://www.southeastevotuners.com/fo...topic.php?t=41

The most boost I am seeing is 6 lbs. I am at 5* in the load sites you mentioned, no knock, but won't build more than 6lbs. Its currently at 5750 RPM, I tried it at 6250 and used your same method with modifying the 6000 and 6500 timing cells. Same thing, still 6lbs. Is there anything that I am missing, maybe I have a boost leak? Any help would be greatly appreciated.

 

Interesting ... to be honest, I've not tried that method on an VIII. I've implemented it successfully on several IXs though. The obvious question is, are you going to full throttle after the limiter engages?

 

Yes, I bring the rev up fairly slow to the limiter, then when I am about at 5500 (limiter at 5750) I floor it. It will build about 6lbs and just stay there. The car is not knocking at all while I am on the limiter. I'm gunna try to tighten the APS bov as it might be leaking.

 

whats your fuel points from 120-160? bring it down to 10.5 @ your target rpm for your stationary rev's see what happens. Keep the timing the same.

from load cells 120 to 160 and rpms cells 5000 to 6000 have you timing @ 6 and your fuel points @ 10.5

 

The cells read 12.1 11.4 11.0
.......................12.5 11.6 11.0

(Sorry for the periods, it was the only way I could get it to be spaced correctly.)

That is the 5500 and 6000 RPM rows.

The timing was at 6. I'll try to richen it up in this area and see what happens.

 

Is 5750 RPM ample for the stationary rev limit on a evo9 turbo? I know that is what TouringBubble has in his tutorial, but is this a good launch RPM.

The thing that leads me to believe that I have a small boost leak is that even when I raised the limiter it still only hit 6lbs.

 

I think somebody can explain this but i think -10 is advanced timing, 30 or more would be retarded? "The numbers in the timing map correspond to at what degrees of crank shaft rotation to fire the spark plug. These are measured in degrees before top dead center (BTDC)." "“Timing advance” refers to the number of degrees before top dead center (BTDC) that the spark will ignite the air-fuel mixture in the combustion chamber during the compression stroke. “Timing retard” refers to the number of degrees that ignition is delayed after the point that would have resulted in generating maximum power." And i think the real antilag should be retarded timing?? Or why would the ecu retard the timing on knock? To get antilag?

 

-10 is retarded timing

30 would be very advanced

 

there is retarding and then there is RETARDING

anywhere between -10 and -30 is antilag retardation

 

But isn't anti-lag ignition cut by super retarded timing. Even if you set stock two-step to -30 it would still be fuel cut correct?

In other words just setting timing to -30 would not really get stock ECU to do anti-lag. You would need to also add lots of fuel correct?

 

Exactly. In my experience, you don't need to be in negative (retarded) timing to build boost on the limiter, you just need less advance.

 

I've found that it takes about -15º to get ignition in the manifold at around 5000 RPM.
